Abstract

A terminal connector for high-current electrical cables includes an electrically-insulating casing of resin-impregnated glass fibers surrounding an end portion of an electrical cable, and a conductive member connected to the end portion of the cable and extending through an axial end of the casing. The casing has an inner collar which cooperates with two movable nuts to adjustably mount the conductive member in an axial end of the casing, and an outer collar to secure the casing to a base plate. The conductive member is formed with an annular groove which receives a resilient sealing ring. The sealing ring slides along an inner circumferential wall of the casing and seals the interior of the casing from its exterior throughout the entire adjustment range of the conductive member. A protective electrode attenuates electrical fields in this axial end, and an electrically-insulating housing having a fluid medium contained in its interior surrounds the casing.

Dependent claims

A terminal connector for electrical cables, particularly high-current electrical cables, comprising an electrically-insulating casing having a circumferential wall bounding an interior for accommodation of an end portion of an electrical cable, and an end region formed with an opening;

a conductive member having an inner portion located within said casing and being connectable to the end portion of the cable, and an outer portion extending through said opening outwardly of said casing;
adjusting means for movably mounting said conductive member through a range of positions relative to said casing;
and means for sealing the interior of said casing from its exterior including during operation of said adjusting means, said sealing means including an annular projection located on said inner portion remote from said opening, said projection extending in radial direction towards said circumferential wall and being formed with a circumferential groove, said sealing means also including a resilient sealing element accommodated in said groove and having a side facing and in sliding engagement with said circumferential wall so as to seal the interior from the exterior of said casing through the entire adjustment range of said conductive member.

A terminal connector for electrical cables, particularly high-current electrical cables, comprising an electrically-insulating annular casing having a circumferential wall composed of circumferential convolutions of glass fibers impregnated with epoxy resin by a filament winding technique, said casing surrounding an end portion of an electrical cable and having at opposite axial ends of said casing integrally-formed outer and inner collars which extend generally in axial direction, said inner collar being formed with an opening at one of said axial ends;

a conductive member having an inner portion connected to said end portion of said cable, and an outer portion extending through said opening at said one axial end of said casing, said conductive member also including a threaded section;
adjusting means for adjustably mounting said conductive member at any of a plurality of positions relative to said one axial end of said casing, said adjusting means comprising positioning means in threaded engagement with said threaded section for positioning said conductive member at an axial end of said inner collar at a selected one of said positions, and securing means also in threaded engagement with said threaded section at another axial end of said inner collar for securing said conductive member at said selected position;
and means for sealing the interior of said casing from its exterior including during operation of said adjusting means, said sealing means including an annular projection located on said inner portion remote from said opening, said projection extending in radial direction towards said circumferential wall and being formed with a circumferential groove, said sealing means also including a resilient sealing element accommodated in said groove and having a side facing and in sliding engagement with said circumferential wall so as to seal the interior from the exterior of said casing at all of the positions of said conductive member obtained by operation of said positioning means and said securing means.
